Experienced teachers, working for The Centre for Industry Education Collaboration (CIEC), have created over 100 teaching and learning resources and a suite of interactive and informative websites for use by teachers and students. They show how science works in real-life contexts and demonstrate how the chemical...

The Centre for Industry Education Collaboration (CIEC) has produced a large number of educational resources that help to illustrate the practical application of curriculum science and technology in real life contexts. With a strong emphasis on student investigations, the resources in this collection allow students...

This set of resources was provided by Centre of the Cell, an educational and health charity which aims to raise career aspirations and improve educational attainment, improve the lives of young people from disadvantaged backgrounds, inspire the next generation of healthcare professionals, widen participation in...

Chameleon bubbles are formed when a sodium alginate solution is dropped into a calcium chloride solution.  The bubbles are filled by an acid‐base indicator solution; so, adding the beads to acids or bases leads to colour changes inside the bubbles by diffusion and pH change. Students can learn about acids, bases,...

These downloadable videos are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce ideas of the energy changes which accompany changes of state.

Work done in this Nuffield 13 - 16 module followed from the D unit called ‘Particles at work’. This D unit provided enough material for eight double periods during a Further Science course and built on the content of the S units for Single Science. The teachers’ guide...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Calculate momentum using p = m x v.
• Describe what happens to the motion of objects colliding head on. 
• Determine changes in momentum, Δp.         
• Explain and use...

Let battle commence! An interactive activity from the Association for Science Education (ASE), where students use video clips of displacement reactions together with animations to investigate the Reactivity Series for metals.

This book, from Unilever, focuses on the science of industrial processes. The book begins with the example of the manufacture of coconut monoethanolamide – a material which stabilises foam in surface active systems, to discuss the common unit operations of mixing, pumping, filtering, evaporation, distillation and...
